Tibetan monks and nuns spend their lives studying the inner world of the mind rather than the physical world of matter. Yet for one month this spring a group of 91 monastics devoted themselves to the corporeal realm of science. Instead of delving into Buddhist texts on karma and emptiness, they learned about Galileös law of accelerated motion, chromosomes, neurons and the Big Bang, among other far-ranging topics. Many in the group, whose ages ranged from the 20s to 40s, had never learned science and math. In Tibetan Buddhist monasteries and nunneries, the curriculum has remained unchanged for centuries.
